BrownfieldPrimghar, O'Brien, Iowa · City of Primghar - (IA)
Primghar is a oil plant in Primghar, O'Brien, Iowa, retired 2022-12-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 1 MW of generation, so the grid hookup, transmission rights, and often cooling-water access are already in place — collapsing the speed-to-power timeline versus a greenfield build.
